reactions proceeded smoothly by ex situ formation of SO2 by utilizing a two‐chamber system in combination with the SO2 surrogate. Furthermore, we report the first direct aminosulfonylation between aryl iodides and amines. Broad functional group tolerance is demonstrated, and the method is applicable to pharmaceutically relevant substrates, including heterocyclic substrates.
据报道,一种新的SO 2替代品价格便宜,工作台稳定,并且可以从大宗化学品中分两步进行访问。5分钟内即可实现基本完全的SO 2释放。通过利用两室系统与SO 2替代物组合异位形成SO 2,八个已建立的磺酰化反应顺利进行。此外,我们报告了芳基碘化物和胺之间的第一个直接氨基磺酰化反应。证明了宽泛的官能团耐受性,并且该方法适用于药学上相关的底物,包括杂环底物。
